qcacld-3.0: Send NDI del rsp in NAN_DATA_DISCONNECTED_STATE state

Browse Source 
NDI delete response is sent to userspace only when NDI is in
NAN_DATA_NDI_DELETING_STATE state. But NDI could be in
NAN_DATA_DISCONNECTED_STATE state if cleanup happens through
NDP_END_ALL path. Driver doesn't send response to userspace in
this case.
Send the response to userspace in NAN_DATA_DISCONNECTED_STATE also
as the application might be waiting for NDI delete status.
Also, use set/get APIs and avoid accessing NDI state directly.
